Despite the fact that the pair correlation functions can be unphysical, the resulting singlet density and charge profiles are as good as those obtained from the more complex hypernetted chain approximation and are in excellent agreement with computer simulations.
If further statistical knowledge is available, this solution can be modified and a better estimation is obtained; however, this makes the approximation process more complex.
But a larger number of angular intervals will result in a more complex decision process and the approximation is useful only if it is amenable to efficient implementation.
Sometimes the effort to render a given original in a given medium requires approximation and elaboration of various sorts, so that any rendering of the given original in the given medium will be correct only up to a point and incorrect thereafter (such is approximation) and more complex or longwinded than the thing rendered (such is elaboration).
Thus, the interpretation of cell subunit velocities in terms of forces has to be considered as an approximation to more complex internal processes within the cell".
HOMA-IR has been shown to discriminate across race and ethnic groups and provides a good approximation of more complex tests [ 60].
Noteworthy, such Hill functions based model provides a simple yet adequate approximation of more complex response functions required to describe real promoters (see Supporting Information Section 3).
Though they played an important role in the development of basic population genetic theory, the analysis of more complex evolutionary scenarios typically involves approximation with other types of models.
Thirdly, we should also consider that the discrete lifestyle categories in which we have classified our population samples (pastoralists, farmers or agro-pastoralists) are rather gross approximations of much more complex subsistence strategies.
However, deviations can be long and persistent and the mean can shift, so that GBM could provide a better approximation than the more complex MRM, especially considering that the data covers a relatively short time span.
